a) Assigned "Feedback" to a "Pan" knob of my nanokontrol2 by midi learn function of Aufxdub, the result parameter moved by a number of "step" like 50% , 70% , 130%. How can I make the parameters moving gradually? b) after I turned the above assigned knob. the pan on auria moved at the same time. is it possible to make the knob independently for aufx? c) tried using the delay fx builtin from auria, but some unexpected noise created. is an new iPad air2 can help for stabilities?
